Hi,

Im having a problem with my Grande Punto T-Jet. Ive had the car around 6 weeks. Its been upgraded with the vl37 turbo along with abarth injectors and has been remapped. When i 1st got the car it pulled like a train and i had no problems. It boosted to 22psi and settled at around 18psi. Now the problem im having is all of a sudden it will only boost to 10psi and it runs terrible especially when giving it a little then a day or 2 later i get the engine management light comes on. I bought a little diagnostic code reader and plugged it in and got the code P2227 , Barometric pressure circuit range/performance. I cleared the code and once again my little GP shot off only to low and behold do the same again a couple of days later. Only boosting to 10psi and running like s**t and eventually the engine management light comes on and same again when the fault is cleared. Its really starting to get at me because when its running right its an awsome little car. Ive been thinking map sensor or tmap sensor but im really not sure. Any ideas anyone pleeeeaaassseee

Find an other original bosch map sensor to test it.
